Gas turbine electric power generation equipment

摘要

A gas turbine electric power generation equipment comprises: a humidifier (3) for increasing at least one of a quantity of steam, relative humidity, and absolute humidity of air: a combustor (5) for generating combustion gas by humidified air obtained by said humidifier (3) and fuel; a turbine (6) driven by the combustion gas generated by said combustor (5); an electricity generator (7) driven by said turbine (6) to generate electricity; a water heater (9) for heating water supplied to said humidifier (3) by heat of the burned exhaust gas discharged from said turbine (6); and a water recovery unit (10) for cooling the burned exhaust gas discharged from said water heater (9) to recover moisture in said burned exhaust gas. Further an exhaust gas reheater (11) is provided for heating the burned exhaust gas discharged from said water recovery unit (9) by a part of water obtained by being heated by said water heater (9).
